Hosting mega-sport events can benefit various areas, including the economy, society, culture, and environment. In detail, a sport event not only promotes the sale of sporting goods and the operation of sports facilities, but also affects various corporate activities such as promotion, advertisement, and product promotion of sports as an opportunity and means for sports to develop into an industry itself. In addition, the promotion effect of not only the host city, but also the companies and tourism resources that are located there can promote the competitiveness of local industries and vitalize the local economy and exert various influence on the community and residents, including enhancing the image of the host city and raising the brand value. It is true that mega events such as the Olympics are national events that bring together the capabilities of the host region, drawing attention from the public through direct and indirect positive economic effects such as enhancing the brand image of the hosting countries, creating jobs, and boosting tourism. Unlike the Summer Olympics and the World Cup, however, winter sports events involve huge investments in building infrastructure for stadiums, athletes villages, and other facilities because the number of participating countries and athletes is small and the games are held in areas away from the city. In addition, the use of facilities is relatively difficult compared to summer sports events as they are often held in sparsely populated mountainous areas. Therefore, due to the failure of post-utilization of one-time installations, in which the competition is held in a flashy manner amid the concentration of global attention, its role and function are extinguished after the event, so the government is facing serious reality such as huge facility maintenance and interest repayment on investment costs. Therefore, this study considered the post-use of mega-sport event facilities and reviewed the plan for post-use of the winter sports stadium, and based on this, presented strategic measures to maximize the post-utilization of sports facilities to increase the legacy of mega-sport events, especially winter sports events. The following conclusions were obtained: First, it is necessary to maximize variable elements in the stadium construction phase to enable the use of various facilities(multi-purpose complexes, multi-functional facilities, mobile facilities, etc.) Second, to minimize the construction costs of sports facilities and avoid excess or redundancy, the distribution of sports facilities and the selection of sports hub cities should be made (selection and concentration considering sports events and venues) Third, a construction plan is needed to cover facilities targets not only for professional athletes and local residents, but also for visitors and travelers(overcoming the limitations of winter sports and demographic limitations of host cities, and reviewing the utilization of tourists). Fourth, various programs related to winter sports need to be developed (increasing efficiency in the utilization of winter sports facilities, linking the cultural industry such as four-season entertainment and concert halls). Fifth, they need to be commercialized for tourism(attracting foreign visitors and tourists through the development of various tourist products, such as sports experience and stadium tour).
